I used .asc for ASCII armored (using --armor) encrypted messages.

But what extension should I use when encrypting file.tar.gz for example?

    @VipulNair It doesn’t, but I would like to use the extension that people expect for this type of file. – sunknudsen Jul 24 '20 at 11:52

.asc is appropriate for all ASCII-armored output, even if the input file was in a binary format. Traditionally the original filename will be maintained so that the recipient knows what to expect once they've decrypted the file, e.g., file.tar.gz.asc.

    Yep, typically .asc for ASCII armored output & .gpg for binary output to be complete. – Esa Jokinen Jul 24 '20 at 13:53
  • gowenfawr, do you agree with @EsaJokinen? – sunknudsen Jul 24 '20 at 14:22

    @sunknudsen I agree that .gpg or .pgp are the most common options for non-ASCII-armored GnuPG encrypted files, with .bin being a rarer but still present choice for some people. Interestingly the choice of .gpg or .pgp may not have anything to do with whether the user is using GnuPG or PGP. There's just less consensus for binary files than ASCII-armored files. – gowenfawr Jul 24 '20 at 15:04
